The present article investigates the application of the penalty function method in the analysis of behaviour of viscoelastic materials, particularly silicon rubbers, under dynamic loading. To perform the analysis, the mathematical model of the object was chosen, and the Matlab code for the mathematical model was developed. The dynamic force was applied to the given model. To find the most precise element describing the behaviour of elastic material from some set of available alternatives, the penalty method, which replaces a constrained optimization problem by a series of unconstrained problems, was used.
